Distribution of Endophyllum sempervivi (Pucciniales) in Ukraine

Abstract

Epiphytotic development of the rust fungus Endophyllum sempervivi was recorded in May 2016 in the cemetery of Borzova village (Volhynian Region, Ukraine) on Jovibarba globifera, a host species and genus new for Ukraine. In northern Europe ((northeastern states) and Canada (Ontario) E. sempervivi occurs beyond the area of natural distribution of Sempervivum and Jovibarba; however, it is apparently absent in Morocco, Spain south of the Pyrenees, Italy south of the Alps and in west Asia (the Caucasus) despite the presence of indigenous species of Sempervivum. A list of all localities in which E. sempervivi was recorded in Ukraine is provided. The article is illustrated by micrographs obtained by scanning electron microscopy.

“…The infection is observable especially when the plants produce the first leaf rosettes. The species is present in Europe, including the Italian Alps, USA and Canada (Tykhonenko and Heluta 2017 (Amelanchier, Crataegus, Cydonia, Malus, Pyrus, and Sorbus) as alternate hosts and species of Juniperus and Cupressus (in Europe) as telial hosts (Kern 1911, Helfer 2005). The collected specimen had hypophyllous roestelioid aecia on gall-like protuberances growing on Pyrus amygdaliformis Vill.…”
